• Used Slime on previous bike, Continental tubes with removable cores and stripped out an old valve to make a filling adaptor, and Schwalbe Marathon Plus tyres did 2500 miles without a single puncture and holds pressure indefinitely - you need to use an old valve attached to a Presta-Schrader adapter as the filling tube provided is meant for Schrader

    That was on 700*28 tyres and used 2oz (about 50g) in each wheel, and didn't notice any wobbles or funny handling - new bike has 700*23 and because I didn't have any other bikes that needed treating with Slime I used half a bottle (4oz/100g) in each wheel, and when the wheels are spun by hand there is a definite wobble until the Slime is spun round the circumference of the tyre

    +1 for decent tyres as first line of defence though!
